Title: Analog-digital converter
Inventor: AKAGIRI KENZO
IPC: H03M1/68
Filed: 1985-02-21
Abstract: PURPOSE:To attain miniaturization, low cost and power saving of the titled converter by detecting saturation information from an output of a sequential comparison transistor (TR) so as to control a converting factor of a multiplication D/A converter and extracting a digital output signal from the output side of the sequential comparison register. CONSTITUTION:A potential of an inverting input terminal of a comparator 23 is 0V at the initial and the said 0V is compared with an analog input signal applied from an input terminal 20 via a sample-and-hold circuit 21. When the analog input signal is larger than 0V, the output of the comparator 23 is 1 or +1 and the sequential comparison register 24 keeps the MSB to 0, and conversely when the analog input signal is smaller than 0V, the output of the comparator 23 is 0 or -1 and the register 24 keeps the MSB to 1. Similarly, each bit in the register is decided sequentially. Further, in this case the saturation information is detected from the output of the register 24 by a detector 28 or the like, the converting factor of a D/A converter 22 is controlled to compress the dynamic range. Then miniaturization, low cost and power saving are attained.

Title: Communication terminal equipment
Inventor: KATO YOSHIBUMI
IPC: H04L69/40
Filed: 1990-02-14
Abstract: PURPOSE:To prevent theft of a terminal equipment and illegal use of the terminal equipment by operating a measuring means after a broken line with a host computer is detected and disabling the use of the equipment when number of times of use of the communication terminal equipment and its operating time reach the prescribed value. CONSTITUTION:At application of power, a controller 3 decrements a down- counter 2 by 1 and after it is confirmed that the count is 1 or over, an orchestral accompaniment reproduction device 4 is started. The user operates the device 4 to enjoy the orchestral accompaniment. lf the count of the counter 2 is 0 or below, the device 4 is not started. When the controller 3 detects the end of play of one music, a communication controller 1 sends a sales log to a host computer 5. After the controller 3 confirms the normal end, a prescribed initial value (e.g., 10) is set to the counter 2 and in the case of not being normal end, the counter 2 is decremented by 1. Thus, even when the connection to the host 5 is disabled, the device is used till the count of the counter 2 reaches 0 or below. Conversely, even when the communication line is broken due to illegal use or the terminal equipment is stolen, the equipment is used only up to 10 times.

Title: Communication system
Inventor: WADA AKIRA
IPC: H04L5/16
Filed: 1988-02-16
Abstract: PURPOSE:To prolong the distance of a transmission line by calculating the distance and controlling the timewise gap so that the time of transmission/ reception of a 2-way data signal is within a prescribed time when the time of the transmission/reception of a 2-way data signal is brought into a prescribed time based on the distance of the transmission line. CONSTITUTION:When a reception circuit 9 of a master equipment receives a data signal from a slave equipment, whether or not a data signal is transmitted/received between the master equipment and the slave equipment within the time T is judged. When the time exceeds the prescribed time T, a transmission distance calculation circuit 5 calculates the distance of the transmission 11 between both the equipments. Then the data relating to the calculated distance of the transmission line 11 is sent to a slave side guard time data generating circuit 7 to decide an optimum guard time TGB for the slave device. Thus, when the distance of the transmission line 11 is long, the guard time TGB of the slave equipment is set short and the transmission of the data signal between the master equipment and the slave equipment is attained within the prescribed time T.
